The stent is a device to widen the ureter.

It still hurts, but I didn't care. > Imagine a constipated zombie at the keyboard.Yeah, I remember that feeling in the ER a couple of times. When they sent me into the x-ray lab for an IVP the dye backing up behind the stone would both make it start hurting all over again and push the stone out of the kidney. They've never actually x-rayed one in the kidney until the one I had to have lipsotrypsied. I think it's been nine in total.> >The ultra sound system does seem to break up kidney stones pretty thoroughly. > > Only if the stones are not very dense. My stones don't qualify.Mine didn't get broken up so thoroughly, but enough that the pieces eventually passed. The doctor was an older guy who didn't give a shit anymore and worked the system to his own advantage. He first tried going in after the stone through the ureter but the stone was too large to take out that way. He claimed he couldn't see that on the x-ray. I'm calling BS on that. He just wanted to bill for the procedure. Later he was treating my cousin and I heard the phone call where my cousin needed his weekly prescription of pain killer to be renewed and the doc told him he saw where my cousin has scheduled the procedure with someone else who would schedule it sooner. My cousin wasn't going to get his pain meds unless he rescheduled with this doctor! This was on a Saturday when there was zero chance of getting a prescription from any other doctor. What a shit! The hospital has a new wing named after that doc now. Rick C. Tesla referral code - https://ts.la/richard11209

Plenty of cells that test well above 3000 ma-hr. However, none are even close to 6800 ma-hr. Also note that the Ultrafire BCR18650 "4000 ma-hr rated" cell is included in the testing showing the highest internal resistance of all the cells tested.

Given the amount of his life he spends doing epic day-night hikes (60-170km without stopping, and breaking speed records in his 60+yr age group) and his 40-year career designing, building and installing satellite ground station hardware, I tend to trust his measurements more than I'd trust a data sheet.

The world record breaking capacity that Panasonic have managed to achieve in this size of Lithium cell, stands at 3600mAH. Genuine 18650s are more typically 1200 to 2200mAH. The very first of these Ultrafire fakes started off several years ago with a capacity claim for 3600mAH, matching the industry leader and subsequent cons have simply kept inflating the capacity claims in the hope of enticing yet more technically clueless consumers into buying such fake goods. There are plenty of youtube videos demonstrating the abysmal capacity, often fake cells with a much lower capacity and cheaper cell mounted inside with perhaps a bit of gravel to make up for the expected weight of a genuine article. <https://www.youtube.com/watch?v=gGF9DZcBric> makes a good starting point for your youtube odyssey into the murky world of Chinese 18650 fakes.
